Chicago is celebrating the 100th Anniversary of Daniel Burnham's Plan of Chicago. They have erected a Burnham Pavilion that, at night, is interactive in that the colors change in response to activity (usually, kids running around the pavilion). During the day, you can wander through the pavilion and get different frames of the Chicago skyline surrounding Millenium Park.
I learned on Wednesday, while watching a new documentary about Daniel Burnham, that today (September 4) was his birthday. I also learned that his architectural and urban design expertise spread beyond Chicago, touching Cleveland, San Francisco, Washington DC, and Manila. He had a very strong interest in cities by lakes/oceans due to his childhood home being near a lake. He alwasy wanted people to be able to look out over the water.
